IMPROVEMENT IN KEY-FASTENERS.

Specification forming part of Letters Patent No. 138,272., dated April 29, 1873; application tiled April 2,1873.

I To all whom lt may concern:

Be it known that I, WILLIAM NERACEER, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Key Fastener, of which the following is a description, reference being had to the accompanying drawing making a part of this specication, in which- Figure l is a side view of the key-fastener in its application. Fig. 2 is a front View.

Like letters of reference refer to like parts in the several views.

The object of thisinvention is twofold: First, to retain the key in the lock so that it cannot be turnedtherein from the outside, thereby making the door secure when locked, as the lock cannot be picked while the key remains therein, thus making the lock burglar-proof. Secondly, the fasteneris used as a tag attached to the key in order to denote the number of the room, and for the greater safety of the key, a more full description of the device is as follows:

A in the drawing represents a section of a door, of which B is the lock, and C the key. In order to prevent the key from being turned while in the lock one end of a plate, D, is inserted in the bow ofthe key, as shown in Fig. 1, whereas the opposite end is secured to the side of the door by means of a button, E, pivoted to a plate, F, fastened to the door. In

the end g of the plate or tag D is a button-hole, a, Fig. 2, for the admission of the button.

The practical application of the fastener is as follows The door on being locked from the inside, the key is then turned so as to bring the bow thereof to a horizontal position. The upper end of the plate is then inserted in the bow, while the lower end is brought down upon the plateF. Thebutton E is then turned so as to pass through the button-hole a, and is then turned down as shown in the drawing, thereby holding the end in close contact with the plate F, and preventing it from being lifted up.

By this device the key is secured in the lock and cannot be turned from the outside. The plate can be attached to the key, and thereby made to serve as a tag on which the number of the room is marked to which it belongs, or, instead, the owners name.

Claim.

What I claim as my invention, and desire to secure by Letters Patent, is

The plate or tag D, button-hole a, and but ton E, in combination with the key C and door, in the manner as and for the purpose specified.
